Mora,
Yes, that would work. Since its max range is 750A vs 500A you’d need to set bAmp_scale to 24 to account for 1.5x decrease in sensitivity.
There are other options if you’d rather use a LEM. I see the LEM HASS 200S is available at Digi-key. That has a max range of 600A so is more comparable to the Tamura 400A(500A max).
bAmp_scale would need to be set to 19 for that one.
LEM HASS devices are more expensive, but they also have a larger aperture for the bus bar or cable. Tamura is 8mm x 15mm. LEM is 10.4mm x 20.4mm.
My 2/0 gauge cable barely fit into the Tamura aperture even after I stripped off a small section of the jacket.
